Abstract Background Improvement of wheat gerc Triticum aestivum L.) yield could relieve global food shortages. Kernel size, as an important component 1000-kernel weight (TKW), is always a significant consideration to improve for breeders. Wheat related species possesses numerous elite genes that can be introduced into breeding. It thus vital explore, identify, and introduce new genetic resource...

A total of 10 field experiments were carried out during the 1998 and 1999 growing seasons both in the north (Lleida) and the south (Granada and Jerez) of Spain. In Lleida and Granada, the experiments were conducted under both irrigated and rainfed conditions, while the Jerez trials were carried out only under rainfed conditions. Ten durum wheat genotypes were used in this study. Quality determi...

To better understand the source–sink flow and its relationships with zinc (Zn) other nutrients in wheat (Triticum aestivum L.) plants for biofortification improving grain nutritional quality, effects of reducing photoassimilate source (through flag leaf removal spike shading) or sink all spikelets from one side spike, i.e., 50% removal) field accumulation Zn grains two cultivars (Jimai 22 Jimai...

To meet the increased demand for wheat consumption, wheat cultivation in Sudan expanded southward to latitudes lower than 15°N, entering a new and warmer environment. Consequently, wheat breeders developed several wheat genotypes with high yields under these environmental conditions; however, the evaluation of the end-use quality of these genotypes is scarce. In this study, we assessed the end-...

Combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. Parents and hybrids differed significantly for general combining ability (GCA) and specific combining ability (SCA) effects, respectively. The variance due to GCA and SCA showed that gene action was predominantly additive...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...
